TYPE-CASTING MACHINE.

Specification of Letters Patent.

Patented June 15, 1909.

Application filed October 14, 1907. Serial No. 397,400.

To all whom it may concern:

Be it known that l, l'naxu l'lINM'AN PIER- rox'r, a citizen of the United States, tempo rarily residing at llorlcy, county ofSurrey, l'higland, ha\ e invented a certain new and useful lmprovement in Type-Casting Machines; and I do hereby declare the following to b. a full, clear, and exact description of the same. reference being bad to the accompanying drawings, forming a part of this specification, and to the figures and letters of reference marked thereon.

This invention relates to that class of type casting machines in which the mold is equipped with a sectional or divided moldblade for the production of either full body character type or short body space type and quads, and it has for its principal objects to provide improved guiding and holding means for the mold-blade sections, designed to prevent springing and the sticking or, as it is termed, hanging up of said sections in the mold-blade channel or guideway, and to provide an effective mechanism for controlling the relative movements or adjustments of said sections.

To which ends the invention consists in the several novel features of construction, C(Jllll'llllilllfillS and arrangements of parts hereinafter fully described In the aceom iianying drawings illustrating a preferred form of embodimentl igure 1 isa side elevation of the mold and soctional mold-blade actuating mechanism arranged for application to a well known form of type casting machine. Fig 2 is an end elevation, and Fig. 3 is a top plan view of the mechanism shown in Fig. l, with-the addition of a. section of the die-ease forming part of the type casting machine and the omission of the actuating lever for the dI'lV': ing member of the switch mechanism] Fig. 4 represents in perspective on an enlarged scale the mold blade sections detached and separated. Fig. 5 is a similar view showing the two sections assembled with the gage block and top bearing in position.

Similar letters of reference in the several figures indicate the same parts,

lVith the exception of the sectional moldblade and its actuating mechanismthe type casting machine with which the improve ments are shown associatedis substantially that of Patent No. 625,998, of May 30, 1899,

of which L is a section of the'die-caise, F a portion of the centering lever and X a portion of the bridge supporting the die case and centering .pin. As will be obvious other forms of casting machine may be employed. The mold may be of any approved construction and in its general features that rep resented is similar to Patent 752,814, of Feby. 23, 1904, of which A'is the frame or base plate, A the adjustable side blocks, A the movable cross-block, M thefront stop or gage for the mold-blade, A the gage block and top guide, and A t screw for said top guide.

The mold blade channel is" formed between the paralleladjacent faces of the side-blocks A, the latter contacting with the interposed gage blockgto determine both the width of the mold-cavitytand of said channel of which latter the base plate to which the side-blocks are clamped forms the bottom. wall.

The mold blade is ofthc divided or sectional type illustrated in Patents 828,450, of August 11, 1906, and 857,728, ofJune 25, 1907, but differs therefrom in several im portant particulars as will presently appear.

In the rior structures the main or lower mold-blate section was of uniform thickness and extended the full length of the mold-blade channel and in rear of the latter for the reception of the front stop and the cross-pin of its actuating devices, and in order that the gage block. might occupy a central position relative to the side blocks said lower or main section was recessed for its'accommodation and to permit it to be utilized as a top bearing for holding said section to its'seat. The upper or cut ofi mold-blade section resting and taking its bearing upon the upper edge of the lower he adjusting mold-blade section also extended the full length of and beyond the channel. This arrangement, necessitated the employment narrow and long was liable to spring and thus open the joint between the sections at the casting face; moreover, difficulty was experienced in adjusting the pressure on the two sectionsm a manner to maintain the joints closed and at the same time permit the requisite freedom "of motion. To over-' comeor avoid these and other defects and ,to render-the upper section more rigid and dispense with the supplemental to'p bearing therefor the following changes and improve- :ments have been devised: To the upper mold-blade section C whose width closely approx mates that of the xnold-blade chanthe front stop M and the' ot 'block and top bearing A plate C which, is received within the mold-f lade channel is of'the samev thickness asthe=mold-blade"fsection C, excepting-at apointfimmediatelybelow said sectionand- To accommodate plate is added a dependent web or plate C rovided with'two openin s c 0 one for er for the gage The'portion of extending longitudinally thereoi where it is recessed or cut away to a depth equal to or slightly in excess of one half its thickness, and the rear end of said plate outside the 'cl1anne1 may be and preferably is reduced in the same de ree. The-lower face 05 of plate" C and-the ower wall Ofbpening c"-are' in parallelwith' the lower overhanging face 0 of m'o1d-bladei. section C.

C and at the same time preserve effective side bearings b for engaging the wall of-the channel the main or lower mold-blade section B is cut away or recessed at a point above and'in rear of the openingv b, the latter correspondingin location to the previous gage block opening, but

I now ada ted to'r'eceive the thicker portion 1 of plate or that containing side bearings a.

' \Vhe'n' the twosections are assembled the lower edge 0 of plate C' c ontacts with and rides upon the lower face b{ of o'ening b and the lower face 0 of section contacts with the upper face I) of section B, so that by locating the gage block A? in opening 0' of blade C it can be utilized as the top bearg for botlrsections, and a single adjust.-

ment Wlll suflice tohold thesection's together and .upon the bottom of the-'moldblade channel.

Preferably that the section B does not take its side bearino on plate C but directlyupon the .wall 0-? the channel through its bearing sur- The extreme rear end of section B contain ing the cross tpin openin is not reduced but is retained '0 full width, thus providing a gaging surface b agalnst which the rear .extension 0,

the parts are so proportioned clwith the latter,

end of the uppermold-blade section, or its dependingiplate C', ,conta'cts when the cast ing faces 0 the two. sections are in a linement for simultaneous adjustment.

The actuating mechanism for producing and controlling the movementsof the upper mold-blade section C to advance the latter beyond the lower section B, when casting short body type, and to hold said upper section firmly in contact with the alinlng gage b when full body type, are desired, is prefcrably cou led to said section 0, through V blade ,0, t e'latter' being provided with'an notched as at.C or otherwise provided with a se arm of a lever M, pivoted at m to a block N preferably secured to the mold and remov-;

able therewith.

The actuating-mechanism is coupled with lever M7 or equivalent transmitting device,

and 1t compr1ses,-amon its distinguishin elements, a driving mem er D coupled wit a movin arable bearing for one I;

portion-of the casting machine,

such as t e centeringin actuating lever F;

a driven member, sue as lever G, coupled with the upper mold blade section, as by its. engagement with'transmitting lever M and a switching mechanismpreferably controlled from a movin 'part of the casting machine, for example, the die-case L, and operating to determine the direction of motion imparted by the driving to the driven member. In the preferred 'form' of embodiment illustrated the driving member D is supportedto-reciprocate in guides on a bracket -D fast to the frarhe X of the casting machine, and it is coupled with the centering, lever F through the medium of a lever pivoted at E "to bracket D. and provided at one endwith an adjustable bearing E, to receivesaid lever E, and at theopposite end with a retr'acting sprin E Lever E enga es driving member between fixed and yie ding bearings connected to the latter so that the movement derived irom spring IE" will be positively transmitted" hrough the fined bearing, while that deriv ,from cena tering pin lever F will be transmitted through the yieldin bearing. To this end lever E takes its e'aring on the" driving member between the upper end of the latter and a spring D,'-"interposed between a loose washer D resting upon the lever and-an opposing bearing carried by the driving member, such as an adjustable nut on the rod or extension D carried by said drivin" member. The driven member or lever i; is pivotally supported at G on' bracket D and' its lower end is furcated to'form an open or detachable connection with trans-v mitting lever M. 1

The switching mecl'lanism interposed between the driving and driven members, comprises a reversing, or. double cam D? whose oppositely inclined surfaces d d merge into a leading edge or point 03 and a switch or tongue (i movable with relation to the leading edge or point of the double cam in a direction transverse to the'line of movement of said cam, one of said elements (double cam D or switch G) being connected to the driving and the other to the driven member, so that when the driving member is reciprocated it will cause the engagement of one or the other reversed cam surfaces (Zj (Z according to the setting of the switch member, and thereby efiect a move ment of the driven member in the direction indicated by, the engaged cam surface; or, if already in the indicated position, it will retain it there and prevent displacement.

In the present instance thereversingor double cam D is attached to and carried by the driving member D, while the switch G is pivotally secured to the driven member I t i or lever G, the latter provided with studs or bearings G for limiting the motion of said switching member. "When in its normal or inactive position the driving member D is held by spring E with the point of its double cam D beyond or below the free end of switch G so that the latter is free to swing between stops G to present its point on either side of cam D and accordingly as said switch is thrown to the right or left, in Fig. 2, the next ascent of the driving memher will force the upper mold-blade section beyond the lower mold-blade section, so that a short body type will result, orit will force upper mold-blade section back against gage b and thus bring the casting faces ofthe two sections in alinement, to produce full body or character type, the set wise dimension of which will be determined by the usual adjusting devices coupled with the lower mold-blade section.

It may here be remarked that the adjustment of the lower mold-blade section is effected by a retrograde movement of said section and precedes the final descent of the centering pin lever F, hence the movement imparted to the upper mold blade section to bring the two sections into alinement at the casting face does not interfere with the adjustment mentioned"; the spring D" yielding when the two mold-blade sections are properly positioned.

it is obvious that any appropriate and competent means may be applied for shift-' ing and retaining the controllable swlt'ch member G in either of its operative positions. The preferred form of control mechanism illustrated includes a rod J supported in a bearing on bracket D and piv'otally connected to a pin G" carried by switch (i and projecting through a slot in the cover plate D. v

As the character or full body type usually exceed in number the short body space type or quads the machine is preferably arranged to normally maintain the upper moldblade section retracted against the alining gage b but in a.manncr not to interfere with the movements of the mold-blade either when adjusting or ejecting. To this end aspring J is applied to red J (as by being interposed between its bearing on bracket D and a collar .l'' fa t on the rod) in a manner to hold switch G to the right, in Fig. 2, thus maintaining it in position to be engaged by the surface (l' of the cam 'D" so that upon the ascent of the driving member the upper mold-blade section, it' at the time projected, will be retra ted against. the. gage. llazving been brought to the position indicated spring .l serves to retain it there until power is applied to overcome the spring and shift the switch to the opposite side of cam I said spring yielding to the movements of'the mold-plate both in ejecting and adjusting,

while holding the upper mold-blade section in contact with its gage; but should the upper molt'l-blade section be displaced, the switch being still held in position, the next ascent of the driv ng member would replace and lock it in position during thecasting interval, which latter occurs while the centering pin lever F is in its lowermost position.

The imachanism shown for automatically throwing the switch when low body spaces or quads are required includes a rock shaft K sup mrted in hearings on bracket D and provided with one or more arms K in osition to be engaged by the end of. the die? case L when the latter is shifted to the extrcme of one o its two way movements.

to engage a spring interposed between it and collard ou rod J, so that when said shaft is rocked it will move switch (i to the opposite shoulder G" engaged and bring itinto the plane of movement oi cam sur't'acc (Z, to cause. the advance of the upper mold-blade section on thenext ascent of driving member D.

The operation of the mechanism is as foladjust the mold blade preliminary to acast, lever l descends and upon contacting with bearing E it rocks lever E in a direction to lift driving member D through the medium of interposed spring D". The switch G? of the driven member G lies to one side or the other of the double cam D carried by driving member D and in contact with one of the stops G" of saiddriven member, so that as the driving memberrises lever G is rocked or displaced laterally to advance or retract the upper moldbladc scction'.'- 'Ihedirection of. movement depends upon theposition occupied by the switch member G, the latter being set prior to the engagement. of cam low space or-quad is to be cast, thedie-case is brought into such position that by striking a gaiust one of the arms K it will rock shaft Shaft K also carries an arm K in position lows: \Vhen the cross-pin is operated to from that normally K'. and thereby causearin K to advance rod with the front stop, when the end of the mold-blade section will contact with the cross-block. If the next type called for is a full body or character type, the withdrawal of the die-case L from arm K permits spring J to return switch'Gr against the right hand stop G thus bringing it within range of cam surface d so that upon the next ascent of driving member D the upper end of lever G will be shifted to the right, thereby retracting the upper mold-blade section and seating it against gage b where it is retained by spring J until the switch is again shifted.

T e return of the upper mold-blade section C to normal position after a short body type has been cast may be effected by the spring J alone, if of sufficient tension to overcome the resistance of the switch, driven member and parts coupled therewith, in

which event cam surface d would merely operate to lock said mold-blade section in position during the casting operation, and to insure its return should the spring alone fail to accomplish this result; or the spring, iflighter, may operate to simply shift the switch to normal position against the right hand stop and to exert pressure on the moldblade section suflicient in degree to maintain the latter in contact with its positioning gage b f l n-niachines of this class interchangeable molds are employed for diil'erent sizesor character of faces and the actuating mechanism is so organized that this may readily be accomplished without involving any change in the actuating devices further than this, if actuating lever M is supported upon the mold it will be removed .with the latter and transferred to the substitute mold, and if mounted on the frame of the machine, the substitution can be effected without disturbing said lever, the separable bearings pro-. 'vidcd at each end of the level-permitting this to'be accomplished.
